In principle, quantum communication between a sender and an observer can be described as the problem of quantum state discriminaton[1]}. The main purpose of the quantum state discrimination is to establish the optimal strategy for discriminating several quantum states with maximal success probability. So far, several quantum state discrimination strategies have been proposed such as minimum error discrimination[2]}, [3]}, [4]}, unambiguous discrimination[5]}, [6]}, [7]}, [8]} and fixed rate of inconclusive result[9]}, [10]}, as well as suitable measurements for possible implementation[11]}, [12]}, [13]}. However, unambiguous discrimination can be realized only in the ideal case[14]}, and fixed rate of inconclusive result is not theoretically well developed. For these reasons, the experimental implementation of the quantum communication have been mainly focused on the minimum error discrimination.
